“Everything happens so fast. It’s all happening in real time in the sense that, ‘Used to Love You’ came out only a couple weeks after I wrote it,” she said. “The only reason I did that was just being honest. There’s been a lot of dishonesty about me, and I just don’t understand that because it’s just not how I live.”

While Stefani previously revealed that Shelton, 39, inspired the track “Make Me Love You” off her new album, “This is What the Truth Feels Like,” she alluded that a spark brought the record to life.

“I did not think anything. I wasn’t thinking. I was feeling and I was dying,” Stefani explained. “And then I was like, ‘You can’t go down like this! You have to turn this into music. You have to try, at least.’ I was so embarrassed by just everything. I just didn’t want to be that person that just went down after all of that.”
